Get the police off your tail
If you have one or two police chasing you, swerve around things
such as incoming traffic, trees, poles, or any other immobilized
objects. The police may not see it and crash into it. This
gives you an advantage to lose them. If you are way ahead
of the pack and do not feel like having a police on your tail,
if your radar detector detects an incoming radar (or police),
zoom on the road in front of you. See where the police are
parked, and slam into the back of their car. It will be a
hit and run, but the police car will be dead. You will not
even get a yellow star.

When you want to get rid of the cop chasing you at a close
distance, get just behind him so that your front tire is touching
his back tire. Then, turn your car slightly in the direction
of the cop car. The officer will get turned around and end
up facing in the wrong direction. This should give you enough
time to get away. If you are really lucky, he may hit the
other racers and cause a big accident.

If you are cornered, press Reset Car to start back on the
road and lose the cops.

No police
If you drive backwards on any track you will not see any police.

360 powerslide
This trick is tough to pull off and will require some practice
before using it in a race. Get to at least 80 mph. Press the
Analog-stick backwards at an angle in the direction that you
want to turn, so it is inverting your slide. As soon as you
begin to turn, slam and hold the brakes. Force the Analog-stick
sequentially around in an extreme circle. Release your brakes
when you are about 75% through your turn. Slam your accelerator,
and power yourself through the rest of the turn. At the end,
it is recommended that you bank the car for a moment, because
you do not want the it to fly out of control.

Scared opponents
All of your opponents can be scared. If your opponents are
directly besides you, suddenly steer towards them, as if you
were trying to ram their car off the road. They will panic
and veer away from your sudden move. If you are lucky, they
may veer away too much, thus causing them to crash into an
object, slowing them down. You can also do this to police
that are on your tail.

Speedometer
Look closely at the speedometer of the Ford Mustang Cobra
R. The meter goes from 180 to 240 to 210 when displayed in
kph.
